|Apple CD-ROM's are apple branded. Meaning they have a little bit of code in their bios that tells the mac it's an genuine Apple CD-ROM. |
In Mac OS 9. You can use any DVD/CD-ROM so long as you use the "Apple CD-ROM driver" version 5.3.1. Nothing before or after, it has to be that version number.
In Mac OS-X, I dont know of any drivers for it. It might work, or it might not work. I'm using a generic DVD-ROM in my 9600 and it works just fine in both.
Just make sure that the CD-ROM you have is the same standard as the machine your installing it into. IDE-IDE, SCSI-SCSI, SATA-SATA, etc.
